内镜六环连续结扎器的研制与应用

Development of a Multiple Ligator and its Endoscopic Therapy for Patients with Esophageal Varices

研制经济实用的六环结扎器，应用自制结扎器与进口结扎器对肝硬变并食管静脉曲张破裂出血患者进行结扎治疗，并对两组间的疗效进行比较。止血成功率、曲张静脉闭塞率、再出血发生率，自制组９３．８％，８７．５％，０，进口组９４．５％，８７．１％，２．４％，两组间无显著差异（Ｐ＞０．０５）。自制结扎器在质量指标、操作成功率、止血成功率、曲张静脉消失率、再出血发生率、并发症以及术后复发率等方面与进口结扎器相似，但成本明显低于国外同类产品。

The ligatos we have developed is a kind of economical and effective six-ring ligator. Endoscopic variceal ligation(EVL)was performed to treat bleeding from esophageal varices in patients with liver cirrhosis using self-made ligator and foreign multiple ligator .There are similary effects with both self-made ligator and foreign mutiple ligator in the control of variceal bleeding,variceal obliteration and rebleeding(93.8%,87.5%,0 in the group with self-made ligator,94.5%,87.1%,2.4% in the group with foreign mutiple ligator,P>0.05).In terms of the quality index, successful operation rate, hemastatic rate, variceal obliteration rate, rebleeding rate, complications and variceal recurrence rate, the self-made ligator is as good as the foreign multiple ligator, but much cheaper.
